How to Use a Circular Polarizer Filter

Although many old-school film filters are now obsolete in the world of digital photography, a few are very useful. One of them is the round player filler.

The round polarizer can be used to add dramatic effects to your photographs and it is one of the tricks that professional photographers rely on to create bright images with rich colors and dynamic contrasts. However, you need to know how to use it to get the best out of it!

What does a Polarizer do?

Simply put, a polarizer reduces the amount of reflected light that goes into your camera’s image sensor. It’s a way to cut junk light and atmospheric acoustics and allows the camera to capture a clearer, crisper picture.

If you wear polarizing sunglasses on a sunscreen day at the lake, you can see what polarizers can do. With a polarizing lens, the blue sky appears a deep blue and the clouds seem to pop out from the background. The water moves no reflection and you can see deeper than you without your glasses. The polarizing filter can have the same effect on the camera.

How to use a polarizing filter

Polarization above 90 degrees from the sun (or light source) is most effective. Maximum fog will occur when your subject is in a right angle to the sun. At 180 degrees (when the sun is behind you) the polarity will be non-existent. Between these two points, the amount of polarization will vary.

A round polarizing filter screws have two rings onto the front of the camera lens and rotating. To use a polarizer, simply bend the anterior ring to activate the pole.

Look inside the camera when turning on the filter ring. You know that you have achieved polarization because the reflections will disappear and the contrast between the blue sky and the clouds will increase.

Practice with reflection and blue sky when using polarizing filters. Take some pictures of the same scene without maximum polarization and polarization and compare the two. The difference has to be dramatic.

Once you are aware of the effects of polarization you will find its usefulness even if the image has no sky or reflection. These are the two best examples used to explain polarization of effects. Many professional photographers rarely take a polarizer off their lenses, no matter how valuable these filters are.

Drawbacks of a Polarizing Filter

Keep in mind that using a polarizing filter will reduce the amount of time it takes for two or more fonts to reach the camera sensor, so you need to adjust for that. Pick a slow shutter speed (and use a trip if necessary ), select a lower f / stop, or add more light to the scene (at the same angle, if possible).

Low light conditions are not ideal for using a polarizing filter. If you want to cut a reflection late in the day or fill the clouds at sunset, use the tripod.

It is best to set your focus then find the maximum fog points. This is because the ring polarizer is attached to the front of the lens when it focuses and stops polarization. If you want to focus again after polarizing, the filter should still have the normal sensor you placed (unless you change the focus point).

Bought a polarizing filter

Polarizing filters are not cheap and it is important to adhere to the standard when shopping for it. Keep in mind that sharp photographs are produced by good, quality glass and the same attention you put into the optical quality of your lens should go into your polarizing filter.

Do not purchase a linear polarizer for use with a DSLR. These are used for manual focus film cameras and, when they burn light more dramatically than a circular polarizer, they can damage your camera electronics.

When circular polarizers began to use autofocus lenses and complex electronics in film cameras , linear polarizers did not work with the new technology. If a filter simply says ‘polarizer’, it is a linear polarizer. Circular polarizers are always called ‘ circular polarizers ‘. This is very important to search through the explosion of camera accessories tenders!

If you have multiple lenses of different filter sizes, you may be able to get away with a single polarizing filter. As long as the difference in the size of the filter is not too strong, buy a step-up or step-down ring. This inexpensive adapter can come in a variety of sizes and can be used for fitting, for example, a 52mm filter takes a 58mm filter onto a lens
